- controlling body temperature
- the human body temperature must be kept at about 37 degrees Celsius so that enzymes will work efficiently. The core body temperature, deep inside the body must be kept stable
- Body temperature is monitored and controlled by the thermoregulatory centre in the brain. This centre has receptors that detect the temperature of the blood flowing through the brain.
- Temperature receptors in the skin also send impulses to the brain to give information about skin temperature
- The skin looks red when we are hot due to increased blood flow
- Sweating helps to cool down the body. When it's hot more water is lost from the skin so more water must be taken in with drinks and food to balance this loss
